Abstract: The present invention discloses a platform to track and collect data throughout a user's engagement with a mobile device independent of user engagement with any one app. The user may transition between apps without closing an opened app or returning to a home screen. The user engagement data across the apps may be used by data analytics to target ads for the user. The data analytics analyzes the user engagement data to discern the user's interest to generate the targeted ads. The present invention also discloses a platform to deliver and display dynamic, targeted ads on a mobile device at all times, even when the user transitions between apps, or is on the home screen and disengaged from all apps. The targeted ads are displayed more timely in an ergonomically accessible manner to capture a user's attention, increasing the chance of user response and the return on investment for advertisers.

Abstract: An ergonomic graphical user interface in a mobile device allows a user to use the mobile device effectively with one hand. The ergonomic user interface organizes icons representing related application programs into common arcs. Such arcs serve as a convenient gateway to apps of a specific context category and thus enhance the ability to comfortably use the mobile device using only one hand. The advantages are achieved by basing the interface design on ease of interaction with the touch screen using the natural range of motion of the human thumb. Related application programs may share data, information and resources. A sever may interact with the related applications to provide additional services and analytical information based on the shared data.
